On-resistance and gate charge — what they mean for the switching stage
The BSC034N06NSATMA1: The 3.4 mOhm maximum Rds(on) at 50 A and 10 V gate drive keeps conduction losses low in high-current paths. The 41 nC total gate charge at 10 V sets the switching energy. The drive voltage range of 6 V to 10 V means it can be driven from a standard 10 V gate-drive rail, but also works with 6 V logic-level outputs if the application can tolerate the slightly higher Rds(on) at reduced gate voltage.
Package and mounting — PG-TDSON-8-7
The PG-TDSON-8-7 package is a 8-lead PowerTDFN with an exposed drain pad on the bottom. The pad must be soldered to a copper land on the PCB with adequate thermal vias to the inner ground plane; the datasheet's recommended footprint and thermal via pattern should be followed to achieve the rated 74 W power dissipation at the case. The part is surface-mount only, so reflow soldering is the intended assembly method. The supplier device package code PG-TDSON-8-7 is Infineon's internal designation; the industry-standard package name is 8-PowerTDFN.
Active production, no end-of-life concern
The BSC034N06NSATMA1 carries an Active lifecycle status from Infineon. There is no last-time-buy notice or NRND flag on this part. It is ROHS3 compliant, which covers the current EU RoHS exemption list. For new designs, this part is a safe choice without near-term obsolescence risk. The OptiMOS series is a mature, widely used platform, and Infineon typically provides long-term support for these parts.
